4 Claims.

This invention appertains to new and useful improvements in means for restringing tennis rackets and like implements of'sport.

The principal object of the present invention is to provide a tennis racket restringer which can be easily applied to a tennis racket and employed in a convenient and free active manner to restring a racket without difliculty and at an appreciable saving in time.

Another important object of the invention is to provide a tennis racket restringer which takes care of substantially all of the necessary operation incident to restringing a tennis racket.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a top plan view of the restringer applied to a racket.

Figure 2 represents a longitudinal sectional view taken substantially on line 2-2 of Figure 1.

Figure 3 represents a sectional view taken substantially on line 33 of Figure 2.

Figure 4 represents a perspective view of one of the shafts.

Figure 5 represents a sectional view taken substantially on line 55 of Figure 2.

Figure 6 represents a perspective view of one of the clamp shoes.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents a tennis racket frame to be strung with the handle 6 extending therefrom.

The restringer consists of a pair of elongated bars 6T, the bar 6 being substantially longer than the bar I. The opposed faces of the bars Bl are provided with elongated rubber strips 8 for engaging the racket frame 5 to prevent marring thereof and to prevent slipping of the rewinder thereon.

Bolt members 99 extend upwardly through the end of the bar 1 and also through the hook shaped plate H)|ll.

A shaft H is provided for each end of the bar 6 and this shaft consists of the cylindrical portion 12 provided with a reduced extension l3 7 having a pin l4 driven therethrough with the end It will be observed in Figure 2, that each of the bolts 9 extend through an opening 28 in an arcuate shaped shoe 2 l, the contact side of which is provided with a rubber plate 22. The threaded portion of each of the bolts 9 is provided with a wing nut 23.

A plurality of openings 24 is provided in each end of the bar 6 concentrically arranged with respect to the shaft I l and a pin member 25 can be disposed through the corresponding eye member l6 and into the corresponding opening H to retain the string '20 at whatever tautness is desired.

It will be observed, that in first starting to string the racket, the string is knotted as at 25 and then disposed across the frame and tightened by the corresponding shaft H, after which the bars 6-! are shifted slightly sothat one of the tubes 9 engages over the external portion of the string and by tightening through the use of the corresponding wing nut 23, the shoe 2! in place against the string, the string will be retained in this taut position while it is removed from the adjacent shaft reduced extension l3 and trained back across the frame and subsequently attach the shaft II at the opposite end of the bar 6.

This operation is repeated from time to time, bearing in mind to employ the clamp shoe 2! to retain the last section of the string trained while the next section is to be trained.

While the foregoing specification sets forth the invention in'specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to Without departing from the spirit or scope of the invention as claimed hereinafter.

Having described the claimed as new is:

1. A tennis racket restringer comprising a pair of bar members, one of said bar members being provided at its ends with rotary shafts, swingable bearing members on the other bar member for engaging the said shafts and being removable therefrom, means on the bars for clamping the same together against a tennis racket, said means including clamp shoes for engaging and holding a tennis racket string while the racket is being strung.

2. A tennis racket restringer comprising a pair of bar members, one of said bar members being provided at its ends with rotary shafts, swingable bearing members on the other bar member for engaging the said shafts and being removable therefrom, means on the bars for clamping the invention, what is same together against a tennis racket, said means including clamp shoes for engaging and holding a tennis racket string while the racket is being strung, and means for retaining the said shafts in string tightened position.

3. A tennis racket restringer comprising a pair of bar members, one of said bar members being provided at its ends with rotary shafts, swingable bearing members on the other bar member for engaging the said shafts and being removable therefrom, means on the bars for clamping the same together against a tennis racket, said means including clamp shoes for engaging and holding a tennis racket string while the racket is being strung, said shafts being provided with a resilient covering around which the racket string is wound.

4. A tennis racket restringer comprising a pair of bar members, one of said bar members being provided at its ends with rotary shafts, swingable bearing members on the other bar member for engaging the said shafts and being removable therefrom, means on the bars for clamping the same together against a tennis racket, said means including clamp shoes for engaging and holding a tennis racket string while the racket is being strung, each of the said shafts being provided with a cross handle at one end thereof.
